Karen supplements her income by making a necklace that she sells online. Orders for the necklace occur randomly at arate of one order per every 30 hours, on average. Karen is planning a trip which will take her “off the grid” for84 hours. She is leaving her house at6am on Monday morningand will returnThursday afternoon at 2pm. As she leaves on Monday morning, she has filled all orders and hasan inventory of 4 necklaces. She gives her husband instructions to fill any orders that come in while she is away (up to a maximum of 4).
